DESCRIPTIONS  OF  APPARENTLY  NEW  SOUTH 

AMERICAN    BIRDS,  WITH   NOTES   ON 

SOME  LITTLE  KNOWN  SPECIES 


BY  CHARLES  B.  CORY 


Since  the  publication  of  my  last  paper  on  South  American  birds,* 
further  study  of  the  collections  secured  by  the  members  of  the  Museum's 
expeditions  in  South  America  has  brought  to  light  a  number  of  new 
forms  which  it  seems  advisable  to  describe  at  the  present  time,  as  the 
detailed  report  on  the  results  of  the  expeditions  will  not  be  ready  for 
publication  for  some  months. 

Conopophaga  lineata  cearae  subsp.  nov. 

Type  from  Serra  Baturite,  Ceard,  Brazil.  Adult  male,  No.  47264, 
Field  Museum  of  Natural  History.  Collected  by  R.  H.  Becker,  July  18, 


Approaches  nearest  to  C.  I.  lineata  (Wied),  but  differs  in  having  the 
crown  more  rufous  brown,  the  crown  being  lighter  and  more  rufous 
brown  than  the  back;  lores  and  a  narrow  frontal  streak  black;  post- 
ocular  pencil  of  elongated  feathers  entirely  pure  white,  without  any 
trace  of  grayish  at  the  base;  throat  and  breast  orange  brown,  brighter 
than  in  lineata;  middle  of  belly  pure  white  ;  flanks  and  under  tail  coverts 
approaching  raw  sienna. 

Wing,  70;  tarsus,  22  mm.  (tail  imperfect  in  type  specimen). 

Thamnophilus  doliatus  dearborni  Cory. 

More  specimens  have  been  received  of  this  apparently  well  marked 
subspecies.  Compared  with  specimens  from  Merida  (which  I  assume 
to  represent  typical  T.  d.  nigrescens  Lawr.),  T.  d.  dearborni  (from 
Encontrados,  Zulia,  Venez.)  may  be  readily  distinguished  by  the  more 
heavily  banded  abdomen  and  flanks,  heavier  marked  throat,  etc.  The 
female  is  also  darker  in  coloration. 

Dysitharnnus  mentalis  leucobronchialis  subsp.  nov. 

Type  from  near  Lagoa  Santa,  Minas  Geraes,  Brazil.  Male  (not 
fully  adult),  No.  49118,  Field  Museum  of  Natural  History.  Collected 
by  R.  H.  Becker,  January  24,  1914.

338    FIELD  MUSEUM  OF  NATURAL  HISTORY  —  ORNITHOLOGY,  VOL.  I. 

Similar  to  D.  m.  mentalis  (Temm.),  but  wing  longer  and  entire 
throat  whitish  gradually  shading  into  the  pale  yellowish  of  the  under 
parts. 

Wing,  60;  tail,  42;  bill,  13  mm. 

I  describe  this  new  subspecies  with  hesitation,  as  the  single  specimen 
secured  is  somewhat  immature;  but  the  gray  crown,  olive  gray  back, 
and  coloration  of  the  under  parts  do  not  agree  with  immature  specimens 
of  D.  m.  mentalis  which  I  have  seen. 

Dysithamnus  schistaceus  hellmayri  subsp.  nov. 

Type  from  Rioja,  Peru.  Adult  male,  No.  49113,  Field  Museum  of 
Natural  History.  Collected  by  W.  H.  Osgood  and  M.  P.  Anderson, 
July  4,  1912. 

Approaches  D.  s.  heterogynus  in  general  coloration,  being  darker 
gray  than  D.  s.  schistaceus.  The  bend  of  the  wing  and  upper  wing 
coverts  are  uniform  schistaceous  and  there  is  apparently  no  white  inter- 
scapular  patch.  The  bill  is  heavier  and  longer  than  that  of  D.  s. 
schistaceus  and  the  feathers  on  the  crown  have  black  centers.  The 
under  wing  coverts  (except  near  the  border)  are  yellowish  white. 

Wing,  68;  tail,  54;  bill  (culmen),  19;  depth  of  bill  at  nostril,  8  mm. 

This  is  not  unlikely  the  bird  referred  to  by  Hellmayr  as  "subspecies 
b"  from  Yurimaguas  (Nov.  Zool.,  1907,  p.  62),  but  I  do  not  find  that 
it  has  been  given  a  name. 

Cercomacra  huallagae  sp.  nov. 

Type  from  Lagunas,  Lower  Huallaga  River,  Peru.  Immature 
male,  No.  41119,  Field  Museum  of  Natural  History.  Collected  by 
M.  P.  Anderson,  October  16,  1912. 

Entire  upper  parts  slate  gray,  with  the  usual  concealed  patch  of 
white  on  the  interscapular  region;  crown  more  dusky  and  the  back 
more  bluish  slate  color.  Feathers  of  the  throat  largely  black,  but  more 
or  less  mixed  with  gray  (probably  due  to  immaturity).  Breast  and 
sides  of  body  slate  gray,  becoming  paler  on  the  belly,  and  the  feathers 
of  the  lower  belly  very  narrowly  tipped  with  whitish;  upper  wing 
coverts  and  bend  of  wing  immaculate,  with  no  white  anywhere.  Tail 
black,  more  or  less  tinged  on  the  upper  surface  with  slate  color.  Tail 
feathers,  except  the  middle  ones,  very  narrowly  tipped  with  white. 
Wings  blackish,  the  upper  coverts  like  the  back  and  the  exposed  edges 
of  the  quills  very  narrowly  edged  with  slate  color. 

Wing,  73;  tail,  56;  bill,  14  mm. 


AUGUST,  1916.    NEW  SOUTH  AMERICAN  BIRDS  —  CORY.  339 

Although  the  coloration  of  the  throat  would  indicate  immaturity, 
I  can  not  refer  this  bird  to  any  described  form.  The  general  coloration 
is  much  more  slate  color  than  any  of  the  allied  species.  The  longer 
wing  and  grayer  coloration  will  distinguish  it  at  once  from  approximans, 
tyrannina,  sclateri,  etc. 

The  female  has  the  throat  whitish  mottled  with  dusky,  in  this 
approaching  carbonaria,  but  the  belly  is  buffy  ochraceous  and  much 
paler  than  in  tyrannina. 

Female:  Wing,  71;  tail,  53  mm. 

Myrmeci/a  berlepschi  peruviana  subsp.  nov. 

Type  from  Yane  Yacu,  near  Yurimaguas,  Peru.  Adult  male,  No. 
49121,  Field  Museum  of  Natural  History.  Collected  by  M.  P.  Ander- 
son, September  9,  1912. 

Similar  to  M.  b.  berlepschi  Ridgway  from  Chimbo,  N.  W.  Ecuador, 
but  larger;  wing  longer,  and  bill  heavier.  It  also  differs  in  having  much 
less  white  on  the  bend  of  the  wing. 

Wing,  92;  tail,  67;  bill,  22;  tarsus,  30  mm. 

Compared  with  the  type  of  M.  b.  berlepschi  preserved  in  the  U.  S. 
National  Museum. 

Furnarius  leucopus  cearae  subsp.  nov. 

Type  from  Quixada,  Ceara,  Brazil.  Adult  male,  No.  49120,  Field 
Museum  of  Natural  History.  Collected  by  R.  H.  Becker,  June  27, 1913. 

General  coloration  approaching  F.  I.  assimilis  and  the  rufous 
markings  on  the  primaries  about  the  same;  but  differs  in  having  the 
entire  upper  mandible  dark  brown;  the  crown  of  the  head  sepia  brown 
(approaching  that  of  F.  I.  leucopus),  with  the  forehead  showing  a  tinge 
of  rufous.  Back,  rump,  and  tail  approaching  assimilis  in  coloration, 
but  slightly  more  orange  brown;  middle  of  abdomen  and  exposed  under 
tail  coverts  purer  white;  the  basal  portion  of  the  larger  under  tail 
coverts  brownish  black,  not  distinctly  brown  as  in  assimilis;  legs  and 
feet  pale. 

Wing,  93;  tail,  65;  oilmen,  19;  tarsus,  23  mm. 

Two  specimens  of  this  subspecies  were  also  taken  at  Serra  Baturite', 
Ceara,  Brazil,  by  Mr.  Becker. 

Schizoeaca  fuliginosa  peruviana  subsp.  nov. 

Type  from  mountains  east  of  Balsas,  Peru  (alt.  10,000  feet).  Adult 
male,  No.  47677,  Field  Museum  of  Natural  History.  Collected  by 
W.  H.  Osgood  and  M.  P.  Anderson,  May  20,  1912. 


340    FIELD  MUSEUM  or  NATURAL  HISTORY  —  ORNITHOLOGY,  VOL.  I. 

Similar  to  5.  /.  fuliginosa  from  Colombia,  but  differs  in  having  the 
under  parts  more  gray  and  lacking  the  olive  tinge,  except  on  the  flanks, 
and  the  upper  parts  somewhat  brighter  and  more  rufescent  than  in  that 
species.  Forehead  with  a  slight  grayish  tinge;  outer  webs  of  outer 
primaries  paler  and  more  rufescent,  the  rufous  reaching  the  shaft  of  the 
feather  on  at  least  the  second  and  third  (outer)  primaries.  Wing 
averaging  longer. 

Wing,  59;  bill,  ii  ;  tarsus,  24  mm.  * 

Synallaxis  cinnamomea  cearensis  subsp.  nov. 

Type  from  Jua,  near  Iguatu,  Ceara,  Brazil.  Adult  male,  No.  45624, 
Field  Museum  of  Natural  History.  Collected  by  R.  H.  Becker,  July  31, 


Similar  to  5.  c.  cinnamomea,  but  paler;  upper  parts  decidedly  lighter 
rufous,  and  the  tail,  especially  the  under  surface,  much  paler  rufous. 
Wing,  58;  tail,  60;  oilmen,  8  mm. 

Siptornis  orbignii  neglecta  subsp.  nov. 

Type  from  Macate,  central  Peru  (alt.  about  10,000  feet).  Adult 
male,  No.  49111,  Field  Museum  of  Natural  History.  Collected  by 
M.  P.  Anderson,  February  13,  1914. 

Approaches  S.  orbignii  (Reich.)  in  having  the  crown  like  the  back, 
no  black  points  on  the  throat,  and  in  having  the  broad  basal  rufous 
band  on  the  secondaries;  but  differs  in  having  the  under  parts  more 
grayish  brown  (less  pale  cinereous)  and  the  patch  on  chin  and  upper 
throat  deep  chestnut  rufous  (much  darker  and  more  chestnut  rufous 
than  in  either  orbignii  or  ottonis),  and  the  rufous  on  the  upper  tail 
coverts,  tail  and  wings  is  darker. 

Wing,  62;  tail,  82;  bill,  15  mm. 

Automolus  leucophthalmus  sulphurascens  (Licht.). 

Five  specimens  from  Rio  das  Velhas,  Minas  Geraes,  Brazil,  differ 
from  typical  A.  I.  leucophthalmus  (type  in  American  Museum  of  Natural 
History),  while  specimens  from  Bahia  agree  with  the  type.  The  type  of 
A.  1.  leucophthalmus  very  likely  came  from  Bahia  and  the  Minas  Geraes 
specimens  probably  represent  A.  I.  sulphurascens  (Licht.),  which  should 
be  revived.  They  differ  from  specimens  from  Bahia  in  having  the  tail 
and  rump  decidedly  paler  and  much  brighter  rufous;  the  under  wing 
coverts  are  paler. 


AUGUST,  1916.     NEW  SOUTH  AMERICAN  BIRDS  —  CORY.  341 

Xiphocolaptes  promeropirhynchus  iguatensis  subsp.  nov. 

Type  from  Jua,  near  Iguatu,  Ceara,  Brazil.  Adult  male,  No.  49117, 
Field  Museum  of  Natural  History.  Collected  by  R.  H.  Becker, 
September  i,  1913. 

General  marking  approaching  X.  p.  promeropirhynchus,  but  colora- 
tion quite  different  and  very  much  paler  on  the  under  parts.  The 
wings  and  tail  are  decidedly  lighter  rufous  (less  chestnut  rufous) ;  crown 
and  back  grayish  olive  brown,  the  crown  slightly  darker  and  with  narrow 
whitish  shaft  streaks;  rump  and  upper  tail  coverts  bright  rufous;  under 
parts  pale  grayish  brown,  streaked  with  white;  middle  of  throat  dull 
whitish;  no  black  spots  or  bars  on  belly,  these  being  replaced  by  a  few 
obscure  (almost  obsolete)  small  spots  and  broken  bars  of  pale  grayish 
brown;  under  wing  coverts  pale  rufous,  irregularly  barred  with  black; 
bill  blackish  at  the  base,  the  rest  pale  horn  color. 

Wing,  126;  tail,  no;  bill,  41  mm. 

Other  examples  of  this  very  distinct  form  were  taken  near  Jua  by 
Mr.  Becker.  I  have  not  seen  X.  p.  berlepschi  Snethlage,  but  from  the 
description  it  is  quite  different. 

Picolaptes  f  uscus  atlanticus  subsp.  nov. 

Type  from  Serra  Baturite,  Ceara,  Brazil.  Male,  No.  49116,  Field 
Museum  of  Natural  History.  Collected  by  R.  H.  Becker,  July  13, 1913. 

Similar  to  P.  f.  f  uscus  (VieilL),  but  differs  in  being  larger;  the  rump 
and  tail  more  chestnut  rufous;  the  throat  tinged  with  pale  buff,  and  the 
under  parts  more  tinged  with  ochraceous.  The  feathers  of  the  throat 
are  very  narrowly  edged  with  dusky. 

Wing,  87;  tail,  80;  bill,  29  mm. 

Campylorhamphus  trochilirostris  major  Ridgway* 

Several  specimens  of  this  well  marked  subspecies  (which  agree  per- 
fectly in  size  and  coloration  with  the  type  specimen  in  the  U.  S.  National 
Museum)  were  secured  at  Jua  and  Serra  Baturite,  Ceara,  Brazil.  The 
exact  type  locality  being  previously  unknown,  being  given  as  "Brazil," 
I  now  designate  for  it  the  Province  of  Ceara,  Brazil. 

Taenioptera  cinerea  obscura  subsp.  nov. 

Type  from  Sao  Marcello,  Rio  Preto,  Bahia,  Brazil.  Adult  male, 
No.  49125,  Field  Museum  of  Natural  History.  Collected  by  R.  H. 
Becker,  March  18,  1914. 

*Bds.  N.  and  M.  Am.,  V,  p.  269,  1911. 


342    FIELD  MUSEUM  OF  NATURAL  HISTORY  —  ORNITHOLOGY,  VOL.  I. 

Similar  to  T.  c.  cinerea  Vieill.  (nengeta  auct.,  nee.  Linn.),  but  larger; 
wing  longer,  and  upper  parts  and  breast  much  clearer  gray. 
Wing,  140;  tail,  100;  tarsus,  27  mm. 


Muscisaxicola  ruf  ivertex  ruficrissa  subsp.  nov. 

Type  from  Macate,  central  Peru  (alt.  about  10,000  feet).  Adult 
male,  No.  49126,  Field  Museum  of  Natural  History.  Collected  by 
M.  P.  Anderson,  March  3,  1914. 

Similar  to  M.  rufivertex,  but  crown  patch  more  chestnut  and  more 
extensive,  and  under  tail  coverts  tinged  with  pale  rufous. 

Wing,  no;  tail,  72;  tarsus,  24;  bill,  15  mm. 

A  puzzling  specimen  from  Cajamarca,  Peru,  approaches  M.  r. 
occipitalis  Ridgway  in  coloration  of  tail,  upper  tail  coverts,  and  paler 
crown  patch,  but  the  under  tail  coverts  are  tinged  with  rufous  as  in 
ruficrissa. 

Todirostrum  cinereum  cearae  subsp.  nov. 

Type  from  Serra  Baturit^,  Ceara,  Brazil.  Male,  No.  49127,  Field 
Museum  of  Natural  History.  Collected  by  R.  H.  Becker,  July  18, 


Similar  to  T.  c.  cinereum,  but  smaller;  wings  and  tail  shorter,  and 
bill  smaller.  Edgings  of  wing  coverts  and  primaries  white  instead  of 
yellow. 

Wing,  40;  tail,  34;  bill,  n  mm. 

It  is  evident  that  these  differences  are  not  due  to  immaturity,  as  the 
crown  is  entirely  black  (not  gray  on  the  back  part  as  in  immature  birds 
of  T.  c.  cinereum)  and  young  birds  of  T.  c.  cinereum  have  the  wing  coverts 
edged  with  buffy. 

Myiodynastes  luteiventris  vicinior  subsp.  nov. 

Type  from  Yurimaguas,  Peru.  Male,  No.  44859,  Field  Museum  of 
Natural  History.  Collected  by  M.  P.  Anderson,  October  4,  1912. 

Similar  to  M.  I.  luteiventris  Sclater,  but  smaller,  and  the  dusky 
stripe  on  middle  tail  feathers  much  narrower;  outer  tail  feathers  plain 
rufous  with  only  the  shafts  dark. 

Wing,  104;  tail,  82;  bill,  19  mm. 

The  type  specimen  has  the  bases  of  the  middle  crown  feathers  edged 
with  pale  buff  which  may  be  due  to  immaturity.  Compared  with  a 
series  of  immature  M.  I.  luteiventris,  the  same  differences  exist  in  the 


AUGUST,  1916.    NEW  SOUTH  AMERICAN  BIRDS  —  CORY.  343 

tail  markings,  especially  the  middle  feathers.  The  type  also  agrees 
with  adults  in  lacking  the  buffy  marking  on  the  nape,  which  is  present 
in  young  birds  of  luteiventris. 

Myiarchus  tyrannulus  pallescens  subsp.  nov. 

Type   from  Jua,   Ceara,   Brazil.    Adult   male,    No.  48803,   Field 
Museum  of  Natural  History.     Collected  by  R.  H.  Becker,  August  21, 


Similar  to  M.  t.  tyrannulus,  but  belly  somewhat  paler  yellow  and 
breast  much  paler  ashy;  throat  ashy  white,  the  middle  portion  almost 
white.  Back  much  paler  than  in  M.  t.  bahia,  and  more  grayish  olive 
than  in  M.  t.  tyrannulus;  outer  tail  feather  with  a  very  faint  trace  of 
pale  rufous  bordering  the  inner  web. 

Wing,  92;  tail,  90;  bill,  20  mm. 

Pachyrhamphus  niger  tobagensis  subsp.  nov. 

Type  from  Tobago  Island,  West  Indies.  Adult  male,  No.  21016, 
Field  Museum  of  Natural  History.  Collected  by  W.  W.  Brown,  May 
9,  1892. 

Intermediate  in  coloration  between  P.  n.  niger  and  P.  n.  cinereiven- 
tris;  darker  than  the  latter  (compared  with  specimens  from  Santa  Marta, 
Colombia  and  northern  Venezuela)  and  much  more  grayish  (less 
blackish)  on  the  under  parts  than  P.  n.  niger. 

Wing,  76;  tail,  60;  bill,  13  mm. 

The  female  is  paler  and  more  grayish  than  the  females  of  either  niger 
or  cinereiventris  and  the  wing  coverts  are  tipped  with  white. 

For  many  years  I  have  been  satisfied  that  the  Tobago  form  of  this 
bird  should  be  subspecifically  separated  from  birds  from  Trinidad  and 
the  mainland,  but  having  only  a  single  female  I  hesitated  to  do  so.  An 
examination  of  a  male,  however,  still  further  confirms  my  belief,  and  on 
comparing  it  with  large  series  of  typical  P.  n.  niger  and  P.  n.  cinerei- 
ventris I  am  convinced  that  the  Tobago  bird  is  worthy  of  subspecific 
recognition. 

Polioptila  livida  cearensis  subsp.  nov. 

Type  from  Jua,  near  Iguatu,  Ceara,  Brazil.  Adult  male,  No.  49127, 
Field  Museum  of  Natural  History.  Collected  by  R.  H.  Becker,  August 


Approaches  nearest  to  P.  I.  leucogaster  in  coloration  of  upper  parts 
and  head  marking,  but  throat  and  under  parts  are  white,  tinged  with 


344    FIELD  MUSEUM  OF  NATURAL  HISTORY  —  ORNITHOLOGY,  VOL.  I. 

cream  color  with  only  a  faint  trace  of  ashy  on  sides  of  the  breast;  outer 
wing  coverts  broadly  edged  with  white;  white  end  of  third  outer  tail 
feather  more  extensive. 

Wing,  52;  tail,  53;  bill,  10  mm. 

Cistothorus  platensis  tamas  subsp.  nov, 

Type  from  Paramo  de  Tama  (head  waters  of  the  Tachira  River), 
Venezuela.  Adult  male,  No.  44860,  Field  Museum  of  Natural  History. 
Collected  by  W.  H.  Osgood  and  S.  G.  Jewett,  March  i,  1911. 

General  coloration  more  rufous  brown  than  either  C.  p.  mquatorialis, 
meridcs,  or  apolinari,  and  decidedly  smaller  than  the  last;  crown  brown 
with  only  a  slight  tinge  of  rufous  and  obscurely  streaked  with  dusky. 
Coloration  of  upper  parts  approaching  cequatoriatis,  but  pale  streaks  on 
the  back  more  buffy;  under  parts  much  darker  rufous  brown,  with  only 
a  slight  indication  of  whitish  on  the  middle  of  belly  and  throat;  rump 
plain. 

Wing,  48;  tail,  47;  bill,  12  mm. 

Five  males  and  one  female  examined  from  the  type  locality. 

Troglodytes  musculus  beckeri  subsp.  nov. 

Type  from  Serra  Baturit^,  Ceara,  Brazil.  Adult  male,  No.  49115, 
Field  Museum  of  Natural  History.  Collected  by  R.  H.  Becker,  July 
14,  1913. 

Similar  to  T.  m.  musculus,  but  differs  in  having  the  under  parts  paler 
and  more  buffy  rufous;  under  tail  coverts  clear  ochraceous  rufous  with- 
out spots  or  bars;  crown  and  back  paler  and  more  grayish  than  in  mus- 
culus and  the  upper  tail  coverts  brighter  rufous.  From  T.  m.  clarus  it 
may  be  at  once  distinguished  by  its  brighter  rufous  upper  tail  coverts 
and  more  rufous  and  unmarked  under  tail  coverts,  more  grayish  tinged 
back  and  the  pronounced  rufous  buff  coloration  of  the  sides  of  the  body. 

Wing,  52;  tail,  43;  bill,  13  mm. 

Planesticus  rut  iventer  juensis  subsp.  nov. 

Type  from  Jua,  near  Iguatu,  Ceara,  Brazil.  Adult  male,  No.  49114, 
Field  Museum  of  Natural  History.  Collected  by  R.  H.  Becker,  August 


Similar  to  P.  r.  rufiventer  from  Minas  Geraes  and  Rio  de  Janeiro,  but 
differs  in  having  the  upper  parts  decidedly  more  grayish  olive  and  the 
belly  and  flanks  paler  and  more  ochraceous  rufous. 

Wing,  124;  tail,  114;  bill,  20;  tarsus,  33  mm. 

Eight  specimens  examined  from  the  type  locality. 


AUGUST,  1916.    NEW  SOUTH  AMERICAN  BIRDS  —  CORY.  345
